Create a clickable image in a GridView in Android

我设置了一个网格布局,但想让图像打开独立的活动,因为我的代码看起来是这样的:

package android.grid.layout;

import android.content.Context; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.GridView; import android.widget.ImageView;

public class ImageAdapter extends BaseAdapter { private Context mContext;

// Keep all Images in array
public Integer[] mThumbIds = {
        R.drawable.group_off, R.drawable.indoor_off, R.drawable.outdoors_off,
        R.drawable.attractions_off, R.drawable.playcentre_off, R.drawable.animals_nature_off,
        R.drawable.entertainment_off, R.drawable.arts_off, R.drawable.educational_off, 
        R.drawable.museum_off, R.drawable.historical_off, R.drawable.exercise_off,
        R.drawable.swimming_off, R.drawable.restaurant_off, R.drawable.partyhat_off
时 时;

// Constructor
public ImageAdapter(Context c){
    mContext = c;
时 时

@Override
public int getCount() {
    return mThumbIds.length;
时 时

@Override
public Object getItem(int position) {
    return mThumbIds[position];
时 时

@Override
public long getItemId(int position) {
    return 0;
时 时

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView = new ImageView(mContext);
    imageView.setImageResource(mThumbIds[position]);
    imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
    imageView.setLayoutParams(new GridView.LayoutParams(70, 70));
    return imageView;

和阅读的类它看起来像这个

package android.grid.layout;

import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.GridView;

家庭活动扩展活动 {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.grid_layout);

    GridView gridView = (GridView) findViewById(R.id.grid_view);

    // Instance of ImageAdapter Class
    gridView.setAdapter(new ImageAdapter(this));

我该如何让每个点击都能够打开新的独立活动,

Answer 1

在Adpater S GetView 内部添加点击听众

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView = new ImageView(mContext);
    imageView.setImageResource(mThumbIds[position]);
    imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
    imageView.setLayoutParams(new GridView.LayoutParams(70, 70));
   imageView.setOnClickListener(new View.OnClickListener() {

  @Override
  public void onClick(View view) {
   Intent i=new Intent(context,activity.class);
     startActivity(i);
  }

});

    return imageView;
}
